Figure 1: Angiographic catheter (5 French Berenstein, 65 cm length, Torcon NB Beacon Tip, Cook, Inc., Bloomington, IN) inserted from the right common femoral vein through a 9 French vascular sheath.  The tip of the catheter is situated in the upper portion of the inferior vena cava prior to passage through the TAH and into the SVC.
Figure 2 : Superior venacavogram using a straight flush catheter (5 French, 65 cm length, Boston Scientific, Marlborough MA). A high-grade stenosis of the superior vena cava is evident.
Figure 3 : Angioplasty balloon catheter (14 mm diameter Atlas, 7 Fr, Bard Incorporated Tempe, AZ) positioned within the superior vena cava.  Balloon is in the process of being inflated and demonstrates the site of vena cava stenosis (full inflation of the balloon not depicted).
Figure 4 : Further angioplasty performed with a larger diameter balloon. Fully inflated 18 mm diameter angioplasty balloon (Atlas, 7 Fr, Bard Inc., Tempe AZ) across the site of SVC stenosis.
Figure 5 : Repeat superior venacavogram shows no hemodynamically significant residual stenosis.
